A solitary bee leaves an artificial nest. The individual breeding chambers are separated and each contains only one larva. This prevents direct contact with sisters or mothers.

More than 90 percent of all bee species are not organized in colonies, but fight their way through life alone. They are also threatened. Scientists from Würzburg demand more research on the ecology of these insects.

Gas exchange through the stomata: Carbon dioxide is taken in; at the same time a hundred water molecules (H2O) escape for each CO2 molecule that is taken up.

Plants face a dilemma in dry conditions: they have to seal themselves off to prevent losing too much water but this also limits their uptake of carbon dioxide. A sensory network assures that the plant strikes the right balance.

Three examples of the animal species filmed at Kilimanjaro (from left): an Abbott’s duiker, a blue monkey and a black serval.

Numerous large mammals have been documented with video traps on Mount Kilimanjaro by a research group of Würzburg University. The protected areas of the mountain are of tremendous importance for the biodiversity of this animal group.
